Mesa 7i43. Error loading configuration.

Hello everyone,

I am using EMC2 v2.4.2 and I am setting up the configuration for my controller using PNCCONF. I am using a Mesa 7i43 card. EMC2 loads and configures the card fine when using the sample 7i43-small configuration that comes with EMC2. However, when I try to use my configuration from PNCCONF I receive an error.

Can you take a look and let me know if you see the error? I have listed the error log below.

Thank you!

David

Wrong filename?

Thanks guys.

I thought I might have the wrong file name. I am new to Linux and EMC2 so I thought I needed to change the file name in the .ini file. It occurred to me this morning to change the file name in the .hal file. It is now working.

Thanks!

David

What did you change the file name to?
As you discovered pncconf uses the firmware name in the HAL file instead of the INI

Maybe I should remove the reference in the INI? it is for info only. Mind you it says that too

Glad you got it working
please remember Pncconf is in testing (we call it alpha) phase.
Any other problems please let us know.

Hi Chris,

I used the file name that was used in the sample .ini for 7i43s. It is SVST4_4S.bit.

I don't think you need to lose the reference in the .ini. It says plainly that it is only for reference. Being a newbie, I thought this was a mistake so I removed the "#". Of course, it still did not work.

This morning I realized that another file must be calling for the firmware so I thought the .hal file was the next obvious choice. I had a huge smile on my face when I realized that was the answer.

Anyway, the program is great. My fear in using EMC2 was my utter lack of knowledge and experience when it comes to using Linux. However, this program makes it a breeze. Or, at least as much of a breeze as one can expect when designing motion control.

As a side question, where are these firmware files stored?

Thanks!

David

Yes I found the problem too. forgot the board had big and small versions.
it will be fixed in the next bug fix release. Thanks for finding it.
The actual firmware is found at:
/lib/firmware/hm2
then look in the folder for your board (yours is 7i43)
in there you find a link that points to the file 7i43-2/SVST4_4.bit (in your case)
I'm glad you found Pncconf helpful.

Cheers Chris M

Hello Looking for answers in the forum i found your post, now I have the same problem, what did you do to fix that problem, I'm beginner in linux, and I don't know for where starts.
Some peoples said you need to edit the firmware,wrong file name, but the gedit can't open this file, can you help me I thanks a lot.

There are has 3 archives 7i43, 7i43-2, 7i43-4, my card is 400k.
